Despite the burgeoning of interest in the language development of children, there have been relatively few studies that have attempted to address themselves to such a research theme from an epidemiological point of view. Furthermove, there have been even fewer which have combined the epidemiological cross-sectional with the longitudinal approach. Such approaches have been the tradition in Newcastle upon Tyne, as it was in this city that Dr Muriel Morley undertook her now classical study described in her book The Development and Disorders of Speech in Childhood (1957; second edition, 1965; third edition, 1972).
